The address will begin to flash in the display.3. Press the EXIT key to dispatch the ...

KB375 Super Empire Builder & Slot=max

If your throttle says "slot=max", this means that the Super Empire Builder's capacity to handle operating locos is full. The DB150 can run up to 22 addresses at the same time. If you have the "slot=max" message, be sure that all locos that are not running have been released from throttles. This will free up room inside the DB150 for other locos to run. A DCS100 command station can run up to 120 locos so, if you are having this problem often, you should consider adding a DCS100 to your LocoNet system. To Release Locomotives 1. Use the throttle to ...

KB324 DCS100 - Off Line Indicator

The DCS100 automatically shuts down when the heat sink temperature rises to around 45 to 50 degrees Celsius and the OFF LINE indicator will glow red. The DCS100 automatically resumes operation when the heat sink cools down to approximately 40 degrees Celsius. The OFF LINE indicator will also be lit when there is no track status. This is normal and you should not be alarmed.

KB325 DCS100 - Track Status Indicator

The TRACK STATUS indicator shows that there is voltage on RAIL A & RAIL B terminals. The color indicates the type of signal:  If it is orange the track is getting DCC signals with no analog zero stretching.  If the color is green or red then a stretched zero signal is being used to operate a conventional locomotive. When zero stretching is present, the DCC decoder equipped locomotives will read their digital commands normally and perform as commanded. If the Track Status LED is not lit there is no voltage on the track, the track power to the DCS100 may ...

KB583 Programming output voltage and Bachmann decoder programming

Q:  I have a Digitrax Chief system. I wired the programming track as per the manual, using PROGA and PROGB outputs on the DCS100. I turned on the system and checked the track voltage with a Tony Trains RRamp meter, the mainline read 14.2 volts. The programing track did not read anything. I then checked the two wires coming from the DCS100 and they did not have any readable signal. A:  The programing track connected to PROG A and PROG B will NEVER have track power on except the very instant the program message is sent.  So, you would not ...

A Red Status light means the loco is ...

KB267 Super Empire Builder- DB150 Beeps 5 Times

If the DB150 beeps 5 times and shuts down briefly and then comes back on again. It is probably being run too close to its pre-set current limit. To solve this problem, reduce the track current load by setting up additional power districts to provide more total power for the layout. In this case excess current consumption may clip or mutilate some outgoing packets to keep the track current within acceptable limits.

KB844 Zephyr - Programming Error Messages

KB661 DT400 Slot=Max Error Message

Does your throttle say slot=max ?This means that the system's capacity to handle operating locos is full. The DCS100 can run up to 22 or 120 addresses at the same time. If you have the slot=max message, be sure that all locos that are not running are released from throttles or set DCS100 OpSw 44 to closed to increase the number of address slots available to 120. The DCS100 command station that comes with all Genesis, Empire Builder and Chief series starter sets are set with a factory default of 22 slots.  So, once you begin to operate significantly more locos, you may need to ...

KB836 Stealing A Locomotive Address

Stealing A Locomotive AddressDigitrax systems do not allow more than one user to select and run the same locomotive address unless the loco is “stolen” (or shared) by the new user. When an address is receiving commands from more than one throttle, it may seem to be out of control.Stealing is a safety interlock that prevents operators from automatically taking control of locos that are already selected and being run on another throttle. Occasionally you may need to override this interlock to gain control of a loco. This override is called stealing and will result in having a single loco ...

KB135 DB200+ - Troubleshooting Heat Shutdowns

If the DB200+ booster shuts down frequently: 1. Move the DB200+ so that the heat sink has a flow of cool air. 2. Place the DB200+ out of direct radiant heat like sunshine or a room heater. 3. Try direct cooling by using a small fan to blow cool air onto the heat sink. 4. Lower the track load current. 5. Reduce the input voltage from the transformer. If the DB200+ beeps 4 times and shuts down briefly and then comes back on again, it is probably being run too close to its pre-set current limit. To solve this problem, ...

KB459 DT402 & DT400 - Busy or Fail Message During Programming

A  “Busy” message during programming means that the system is temporarily busy.  Simply try the task again.  When the system is no longer busy, you will get a “Good” response. A  “Fail” message during programming means that there is a problem with the locomotive on the programming track.  Check to be sure the loco's wheels are making good contact with the programming track.  Make sure that the decoder is properly installed in the locomotive.   Make sure the connections to the programming track are secure.  Make sure the programming track is powered. 

KB96 DB150 Slot Management for 22 Addresses

The DB150 has 22 “Slots” for locomotive addresses The DB150 command station can run up to 22 loco addresses and throttles at a time. Each of these addresses occupies one of 22 “slots” available in the DB150’s memory. Once those 22 slots are full the system will display the “slot=max” message to let you knot that you need to release some locos if you want to select and run others. The DB150 manages the addresses that occupy slots by assigning different statuses to each decoder depending on how it is being used in the system. This allows the DB150 to ...

KB821 Zephyr-Exit Key

HELP!!!!!!!!If your Zephyr DCS50 display isn't showing you what you expect based on the manual, press the EXIT key to return to normal operating mode. Also make sure that the "Power" is on.

KB362 Atlas DCC Decoder Programming Problem ("d nd") on DCS 50

  My Atlas DCC N-Scale locomotives that are equipped with factory installed Lenz062xf, Lenz063xf decoders will not program using any mode on Program track. I know the system works because I can easily program every Digitrax decoder loco that I have, but if I put an Atlas DCC factory loco on the programming track I get the 'd nd' error code.   There are decoders now present in the market that do not draw enough current for the programming track to reliably detect that they are present, hence the error report of "d-nd". All you have to do is to ...

KB555 DCS100 Command Station/Booster Expanding Available Slots

A slot is a memory location in the command station that holds an active decoder address.  The number of slots is the number of locomotives that the command station can support in operation at a time. When the available slots are filled with decoder addresses, trying to select another locomotive address to run generates the "slot=max" error code.  When all the slots are full you can't select another address until one is released from the system. See Clearing your Command Station's Mobile Decoder Slots below for how to prevent this from happening.The DCS100 Command Station/Booster that is included with Super Chief Xtra and other ...

KB711 UT4 - Steal A Locomotive Address

Stealing, or "sharing" is defined as acquiring control of a loco address that is being used by someone else on another throttle. To ‘Steal’ a loco:1. Unplug the UT4 from the LocoNet port.2. Dial up the address of the loco you want to steal.3. Press and hold the ‘STEAL’ key while plugging the throttle into the LocoNet jack.
